. 'srncrnrcnmmn forming part of Letters Patent No. 753,509, dated March 1, 1904. Application filed Ootcber 24,1903. Serial No. 178,419. (No model.)

To all whom it may concern Be it known that 1,,(JHARLESjK. MUN'NM citizen of the United States, residing at Corning, in the county of Adams and State of Iowa,

have invented certain new and useful Improvements in Electrotherapeutic Devices; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use same.

' My invention relates to, an improvement in devices for the application to the body of electrici'ty for the curing of disease; and' it consistsof a cabinet within which the necessary apparatus is inclosed, means within for gen:

erating electricity and delivering it in graded strength in galvanic, sinusoidal, and faradic form by means of a switchboard having upon 'it switches and necessary contact points,

buzzer, regulating-rods and binding-posts, to electrodes by means of conducting-cords. 4 g l The object is to provide an electrotherapeutic device for generating properly the forms of electricity most applicable for the curing of-disease and which can be placed in the hands of the public knowing that they canuse it properly and that by such use. it will accom-' plish the" desired result without the interven- Myinvention further consists of-so construct'ing the cabinet and generating devices that it is not necessary for the operator to open, examine, adjust, or in any wayinter fere with anything within the cabinet, a part of'one side forming a door which when opened a only discloses to viewftheswitchboard,

- 'My inventionv furtherconsists of means for sealing up thecabinetto prevent the intrusion of inexperienced persons, so that the owner by looking at the seals can tell that the working-parts 'of the instrument have not been disturbed.

In the accompanying drawings, Figure 1 is a view ofthe apparatus when not in use. Fig

2 is aviewbf the apparatus when in use. Fig. 3 shows a view of the switchboard as seen whenthedoor is open and also the method 5 of sealing: Fig. 4 is a somewhat diagramand it is within this that the batteries, the dynamo-electric generator, and the Wires that connect them to the switchboard are placed.

Theonly means provided for gaining entrance.

to this compartment is by removing the top of the cabinet. This is held securely in place by the seal-rod 19, which passes through the cover 49, the head preventing it from passing through entirely. It extends through the bottom 51., a nut'and Washer 20 being put on the end thereof. A seal-wire 21 is run through a hole in the end of the bolt, and a lead seal fastened on the wires prevents the opening of the cabinet without breaking the seal-wire. The door 2being opened discloses the compartments 3 and 3, the latter having in it, attached to the back, all the means necessary for the proper operation of the instrument. The compartment 3 provides a place in which may be put the book of directions, foot-plate,

sponge, cords, &c.

Referring to Fig. 3 and the compartment 3, I provide a pair of terminal-posts 4 and 5, to which any desired form of terminals may be connected, such as a foot-plate 26 and a sponge 27, Figs. 4 and 5. Two levers (Send 7 ,which move over and in contact with-small buttons, regulate the current from the batteries and determine the form of the current desired. Two regulating-rods 8 and 9 regulate the dynamic current, all of which are hereinafter more fully described. A buzzer 22 provides means for interrupting the primary of the inductioncoil for the faradic current and also serves as an indicator for the galvanic current should the batteries become short-eircuited outside of 1 ,the instrument.

Referring to Fig. a circuitB'Z has its extremities connected to the terminal-posts 4 and 5 andhas a suitable switch 6 by which'the circuit may be openedand closed. In the circuit 2}? is interposed a dynamo-electric generate!" The latter is operated by a suitable connected to a contact-button 17. Between the said cells are located other contact-buttons 13, 14, 15, and 16. The switch-arm7 is arranged to engage any of these said contact-buttons 13 to 17 inclusive, thereby cutting out any of the cells from 29 to 32, inclusive; but when the switch is advanced to a contact-button 12 the circuit will be open. hen the switches 6 and 7 are in the position shown in Fig. 4, it will be 'seen that the cells are cut out entirely from the terminal-posts 4 and 5, while the circuit 37 is closed, including the dynamo 23. By

Y may be varied byadjusting the magnetic applying the electrodes 26 and 27 and operating the dynamo-a sinusoidal current will pass through the patient, the strength of which shunts'8 and 9. In order to producea simple galvanic currentthat is, a current that is practically continuousthe switch 6 is moved to button 11 to open circuit 37, while the switch 7 is moved to cut in the desired number of cells. v

Referring to Fig. 5, to produce the faradic current an induction-coil, designated P S, and a vibrator, preferably in the form of a buzzer 22, are used, the primary of the coil and the buzzer being interposed in series in circuit 38. A switch 47 is interposed in the circuit 41, adjacent to the terminal 4, and

may be moved to open the circuit 41 or to connect the circuit to one terminal of a new set of cells 33, the other terminal of which is sisting of a cabinet having three compartconnected to the contact 17 It will be seen that when the switch-lever 47 is moved to the button 43 circuit 41 is opened. The secondary of the induction-coil has one terminal connected to the post 4and the other terminal to a button 40, to which the lever 6 may be moved in contact. It will be seen that there is a contact-button to which each of the levers 6, 7, and 47 may be. moved, whereby the cirzer 22 are placed so that it may be closed by.

moving the lever 7 to the button 17, the primary and buzzer then being in series with the cells 33. Upon the switch 6 being moved to the contact-button the secondary of the induction-coil becomes closed upon the posts 4 and 5 and a faradic current will be transmitted to the patient. In Fig. 5 the levers are so placed that the faradic current would be produced. In Fig; 5 in order to deliver a galvanic current to the patient the lever 47 is placed on the button 44, the lever 6 is placed on the button 11, and the lever 7 is moved to'the buttons 13 14, &c., to cut in the desired number of cells.' For delivering a sinusoidal current the lever 47 is placed on button 43, the lever 7 is placed on button 12, and the lever 6 being placed on button 10 it is only necessary to turn the handle of the dynamo to produce the current.

It is evident that numerous slight changes might be made in the general arrangement and combinations of parts, also in the design of the cabinet, without departing from the spirit and scope of my invention, and hence I would have it understood that I do not limit myself to the precise details herein shown and described; but,

Having fully described myinvention, what I claim as new, and desire to secure by Letters of Patent, is 1 1. In a device of the character described,consisting of a cabinet having three compartments, the largest containing all the generating devices, a door on one side disclosing the smaller compartments in one of which is the switchboard, with switches, buzzer, regulat ing-rods and binding-posts, the combination of a pair of terminals, a circuit having its ends connected with the terminals, a dynamo-electric generator interposed in said circuit,

means for adjusting the current by one or more magnetic shunts, a second circuit connected to said terminals, a source of galvanic current interposed in said circuit, means for cutting out either of said circuits, and crank or other means for driving the dynamo from the outs1 e.
